This is true megaladon6 if he is using the 100LL octane "blue" AV fuel. LL means low lead. Your better off useing The green stuff but its getting harder to find. The blue AV fuel is more commonly found. RACE GAS IS BETTER THAN AV GAS - it is more volatile, and vaporizes more readily. AV gas falls about half way between pump gas and racing in volatility. Just my 2 cents
